As a standard, the K4204 NVR supports four IP cameras (channels). The user can increase the number of channels in the system up to 64 by purchasing additional licenses in the form of serial numbers (XXXX-XXXX-XXXX-XXXX alphanumeric strings). The serial number is to be entered into Input S/N box in the License Management window opened in NuClient application or in the browser.

During activation, the serial number is automatically sent to the manufacturer via the Internet. If the NVR does not have access to the Internet, the license can be activated offline (the activation files are generated on a computer with Internet access).

The activation of additional licenses can be performed at any time, enabling the user to enlarge the IP CCTV system based on Titan NVR(s) without having to purchase new units or make any hardware modifications (except connecting the new cameras). This solution minimizes the cost and time needed to upgrade the system.

The licenses are sold in packages (1, 4, 8, 12, 16, 25, 32, 60), which can be combined to reach the needed number of channels. For example, the user of a 20-camera system will have to buy the K4204 NVR (with 4 active channels) and the license package for additional 16 channels.
